Core, inductance coil are enclosed the land by one by the circle of conducting wire one and are wound on insulation tube, and conducting wire insulate each other, and insulation tube can be hollow
, it can also include iron core or powder core, when there is electric current to flow through a conducting wire, will be generated around this root conducting wire certain
Electromagnetic field, and to the conducting wire that is within the scope of this electromagnetic field induction effect can occur for the conducting wire of this electromagnetic field itself.
The structure of current transformer casing needs the size for meeting Current Mutual Inductance coil, should also have it is easy to disassemble, it is convenient to overhaul
Function.
Such as Chinese patent application (notification number：CN204424035U " transformer casing ") is disclosed, it is characterized in that including shell
Body, housing central section form the hole slot of a hollow installation mutual inductor primary current copper sheet, and hole slot is substantially in be inverted water-drop-shaped, hole slot
The top of inner wall is recessed inwardly to form the second rack of at least one zigzag at least provided with the side wall of first rack, hole slot,
The length of hole slot is equal with the diameter of primary current copper sheet Inner arc, the radius of the height and primary current copper sheet external arc of hole slot
It is equal.The utility model integrated injection molding, it is simple in structure, manufacturing process is simplified, manufacturing cost is reduced, product is whole more
Add beautiful and clean, accordingly improves the electric property of mutual inductor, economic benefit is more obvious, but is a lack of necessary flexible connection
Lid is not suitable for the installation of movable core.
